It also covers electrolyte balances and imbalances, common complications of IV therapy, terms and abbreviations, and references additional resources for more information. The document is a pocket guide that serves as an introduction to IV therapy and the various components involved.
Blood test normal values and it's importanceGOPAL KHODVE
Laboratory tests check a sample of your blood, urine, or body tissues. A technician or your doctor analyzes the test samples to see if your results fall within the normal range. The tests use a range because what is normal differs from person to person. Many factors affect test results. These include
Your sex, age and race
What you eat and drink
Medicines you take
How well you followed pre-test instructions
Your doctor may also compare your results to results from previous tests. Laboratory tests are often part of a routine checkup to look for changes in your health. They also help doctors diagnose medical conditions, plan or evaluate treatments, and monitor diseases.
This PPT is mainly useful for MBBS as well as other branch of Medicine to have an basic idea about Electrolytes. Also about What to see & What to do in cases of Electrolytes Imbalances.
Get the information about various types of syringes and needles. Giving medications by injection requires the use of the right syringe, the right needle and the right part of the body.
Water, sugar and salt are important in helping the body to function. Intravenous fluids (usually shortened to 'IV' fluids) are liquids given to replace water, sugar and salt that you might need if you are ill or having an operation, and can't eat or drink as you would normally. IV fluids are given straight into a vein through a drip.
Making sure that everyone in hospital is getting the right amount of fluid is really important for good patient care. While you are having IV therapy you should be monitored regularly.

IV or intravenous (in-trah-VEE-nus) therapy is a way to give fluids, medicine, nutrition, or blood directly into the blood stream through a vein. IV therapy uses a type of tiny plastic tubing (cannula) that goes into the vein, a needle, and plastic tubing that connects the set-up to a bag of fluid. All together, the pieces are called an “IV.” Intravenous (IV) therapy is administering fluids directly into a vein. It benefits treatment by enabling water, medication, blood, or nutrients to access the body faster through the circulatory system.

Provision of ideal transfusion support – The essence of thalassemia careApollo Hospitals
Thalassemia major is a major cause of transfusion dependence among patients world over. Provision of an adequate, uninterrupted and safe blood supply for these patients is the responsibility of the blood services as well as the society as a whole. Thalassemia management has evolved over a period of time and so have transfusion services. Various technological advancements have been introduced in the last few decades in order to enhance blood safety. Adoption of these newer technologies coupled with increasing awareness about voluntary blood donation in the general population can go a long way in improving the life expectancy as well the quality of life in these children.
The four phases of intravenous fluid therapy: Manu MalbrainSMACC Conference
Manu Malbrain presents the four phases of intravenous fluid therapy. He takes you through the big questions of fluids - What, when, why and how?
To Manu, there are four Ds of fluid therapy: Drug, dose, duration, and de-escalation
Drug
Fluids are drugs. This means, like any drugs, consideration must be taken about the type, indication, contraindication, and adverse effects of fluids whenever prescribing them. The evidence suggests that we should stop using starches in sepsis, albumin in TBI and stop using more than 2L of saline in resuscitation. For maintenance – eliminate the use of unbalanced isotonic fluids, and do not forget to cover daily needs. The bottom line is starting to consider fluids as drugs.
Dose
As Paracelsus famously said “The dose makes the poison”
This holds true when administering fluids. There are different doses for different patients dependent on the indication – whether using fluids for maintenance, resuscitation, or replacement.
Duration
When do you start and stop? You must weigh up the benefit and risk of fluid administration.
Duration should be appropriate – more often than not this means tending towards a shorter duration. Similarly, do not use fluids to treat numbers (such as low CVP or MAP) but rather to treat shock. Finally, fluids can be stopped when shock has resolved.
De-escalation
Water is a problem. Just as hypovolaemia is bad, so too is hypervolaemia.
Weigh up the benefit and risk of fluid removal. Manu describes the ROSE acronym – Resuscitation, Organ support, Stabilisation, Evacuation removal. Essentially, after early management with adequate and goal directed fluids, stop ongoing resuscitation, and move to conservative fluid management (de-resuscitation!)
We need to make good fluids better
So let Manu guide you through the complex world of fluids. Answer the four questions, address the four D’s and remember the four phases of ROSE.
